The world of "self help" often makes reference to the powers of the mind, and that that normally means the power of the sub-conscious mind.
It is of course perfectly correct that the subconscious is powerful, but only as an operating system.
It is powerful in the same way that Microsoft Windows is powerful, it chunters away in the background running 99.9% of what we think and feel and do. But, just like Windows our subconscious operating system has flaws and causes failures and "system crashes".
The powers of the mind in the subconscious areas are considerable and can make a significant difference to how you interpret and respond to what happens to you, to the things that you attract, and to your overall quality of life experience.
But, and this is a very big "but", these subconscious powers do NOT create everything that happens to you. In the bigger picture scheme of things these powers of the mind are actually very limited.
The self-help gurus who tell you that you can have or be anything you want is propagating a "misdirection" (to put it politely) in their overstatement of a partial truth. The reason for this "misdirection" and overstatement of the partial truth is quite simply because they tell you what you want to hear, it panders to what you want to believe, it appeals to your ego. It puts "me" in control of "my life." (Or so we would like to believe.)
However, life is infinitely more complex than we can comprehend, and it also inter-connected and inter-dependent in ways that we do not conventionally fully appreciate.
The real powers of the mind lie elsewhere
At rock bottom, when you get benefit all the words, formulations, doctrines, dogmas, statements of faith and creeds of most of the world's major religions you find a generic truth and that is that the only path to real and permanent personal change and transformation lies in the death of your self.
This is the generic truth that lies at the root of the idea of the Christian "way of the cross" and "death to self" , the Buddhist "decreasing of the self" and "realization of emptiness" and the Islamic jihad in the sense of a personal and internal "holy war" to attain submission to " rutheous living" , and similar expressions in other faith traditions.
The true source of the powers of the mind is in the transcendent or spiritual area of your mind — you could call it your super-consciousness.
What I want to share with you now needs to be approached and considered carefully, and with balance and discernment.
I say this because the reality of the transcendent powers of the mind is by its very nature experiential and thus deeply subjective, and because it is shrouded in paradox.
What we are talking about here is a process that involves an experience of profound inner transformation when what previously thought of as your self with its very limited powers of the mind is transcended by an awareness or consciousness of an infinite larger Self with infinite greater powers.
This process of transformation may happen quickly or more often over a period of time.
As this transcendent awareness emerges or arises you experience a form of "rebirth" or deep awakening. (This is why this is referred to as being "born again" in certain Christian circles.)
Having awoken or been "reborn" you can not "un-experience" it and it leads to a complete paradigm shift where your deepest focus is on this infinite larger Self rather than that which previously thought of as "me".
This does not mean that you completely lose all sense of "me", you do not, a healthy functioning ego is essential to operate in this world. The difference is that your "little self" now knows where it fits into the overall scheme of things and specifically in relation to your transcendent or higher self. Or to put it another way, you realize your true nature and who you really are.
The greatest contribution in the Buddhist expression of this experience is the emphasis on non-duality and a unitive consciousness, and yet paradoxically the greatest contribution in the Christian expression is the relational aspect of your limited self / ego to your highest Self (or God) .
This "crossing of the threshold" and entering into awakening or rebirth does not lead to an instantaneous transformation of your entire existence — this is an ongoing process that takes a lifetime.
Contrary to what many teachers in the major religions will tell you, the words, concepts and context of how you experience this, how you frame it and articulate it does not really matter — this only leads to argument and division. This is not so faith-based as experience based.
You will experience many inner conflicts as the ego (your previously thought of idea of "me") resists this new awakening and you will face many trials, tests and tribulations in your spiritual journey.
If it's that much hassle, why would you want to persist? Simply because there is no other way, you can not "unlearn" what you know. Think of Neo in "The Matrix", once you have taken the red pill everything changes and you enter a new dimension.
The difference between the pre and post awakening state is massive. Your whole reason for being, your purpose in life and your mode of operation and our overall experience of life is very different. You experience a profound sense of peace and of having "come home."
This is where you encounter the greatest powers of the mind as you align yourself and your whole life with an infinite greater plan and purpose.
